Diamond is getting ready to launch xDNA, a technology which will allow you to use the firm's Radeon products in CrossFire on systems with AMD, Intel and NVIDIA chipsets.
We hear that Diamond will make a big announcement at the end of next week, as the company gears up its Radeon products and enables them to work on Intel, AMD and Nvidia chipsets in Crossfire mode.
We're not certain how many GPUs will work in future combinations, but Intel's Bad Axe 2 motherboards with 975X chipset were the first on the market with three PEG connectors (data transfer was dependent on the combination, but you could have x8+x8+x4). This was later followed by numerous motherboards and chipsets - the 680i being the prime example.
Owners of Nforce 680i motherboards are disappointed that the 8800GT will not support three-way SLI. But if that motherboard could be fitted with three Radeon HD 3870 boards, it'd be a remarkable combination.
Judging by how VoodooDNA makes Crossfire work on an Nvidian chipset, we can take a wild shot that xDNA is a subset of technologies unified in a software package, probably a single package for simple installation.
